Description

Technical Field

[0001] The invention belongs to the technical field of prestressed steel strand bundle threading, and in particular relates to an automatic steel strand pulling and bundle threading device. Background Art

[0002] Prestressing technology is a key technology in modern construction, widely used in large-scale infrastructure structures such as long-span structures, aqueducts, and bridges. Prestressing technology involves inserting prestressed steel strands through corrugated pipes within structural openings, applying tension to improve the structure's load-bearing capacity and stability.

[0003] When threading a prestressed steel strand bundle through a corrugated tube, one method currently used is to first thread a steel wire rope through the corrugated tube, then connect the steel wire rope to the prestressed steel strand bundle, and then pull the steel wire rope back so that the steel wire rope pulls the prestressed steel strand bundle, completing the threading of the prestressed steel strand bundle. However, since the steel wire rope is relatively soft and cannot be threaded through the corrugated tube independently, the following methods are commonly used in the prior art to thread the steel wire rope through the corrugated tube:

[0004] 1. Manual pre-threading method: Manually insert thinner rigid materials (iron wire / nylon rope) into the corrugated tube as a lead, and then pull the wire rope through the lead. However, this method is cumbersome, time-consuming and labor-intensive, and has low work efficiency; 2. Rigid rod pushing method: Use a segmented rigid rod to mechanically push, and gradually insert the wire rope connected to the front end into the pipe. However, this method is only suitable for short-distance penetration and has poor adaptability; 3. Double winch traction system: A winch is arranged at both ends of the corrugated tube, and the wire rope is pulled in both directions by setting a pulley. However, this method is costly, occupies a large space, is difficult to arrange, and has poor flexibility. 4. Pneumatic method: Use compressed air to push the wire rope with a traction head into the corrugated tube. However, this method is also only suitable for short-distance penetration.

[0005] In addition, a traction head is required when connecting the wire rope to the prestressed steel strand bundle. When using the traction head in the prior art, the steel strand needs to be stripped first, then upset, and then installed. The steel strand needs to be tied at the other end, which is cumbersome, time-consuming and labor-intensive. Summary of the Invention

[0044] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and by way of preferred embodiments. However, it should be noted that many of the details listed in this specification are merely provided to help the reader gain a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be practiced even without these specific details.

[0045] A steel strand automatic traction and bundle-threading device includes a frame 1, a traction and bundle-threading mechanism 2, a guide clamp 3, and a traction clamp 4. The frame 1 is vertically arranged, and the upper inner side of the frame 1 is movably connected to a frame plate; the traction and bundle-threading mechanism 2 includes a mounting frame 21, a traction assembly 22, and a rigid guide assembly 23; the mounting frame 21 is movably arranged on the top surface of the frame plate; the traction assembly 22 is arranged on the right side of the top surface of the mounting frame 21, and includes a steel wire rope 221; the rigid guide assembly 23 is arranged on the top surface of the mounting frame 21, on the left side of the traction assembly 22, and includes a guide steel strand 231; the guide clamp 3 connects the steel wire rope 221 and the traction end of the guide steel strand 231; the traction clamp 4 connects the steel wire rope 211 and the prestressed steel strand bundle. After the guide clamp 3 connects the traction ends of the steel wire rope 221 and the guide steel strand 231 through the guide clamp 3, the rigid guide assembly 23 drives the steel wire rope 221 and the guide steel strand 231 to pass through the corrugated tube from one end and out from the other end. The steel wire rope 221 is then connected to the prestressed steel strand bundle through the traction clamp 4. Finally, the steel wire rope 221 is retracted and the prestressed steel strand is pulled through the corrugated tube to complete the prestressed steel strand bundle. Since the steel wire rope 221 is relatively soft and cannot pass through the corrugated tube by itself, a steel strand with greater rigidity is used to drive the steel wire rope 221 to move, so that the steel wire rope 221 can smoothly pass through the corrugated tube and connect to the prestressed steel strand.

[0046] The traction assembly 22 includes a traction hoist 222, which is located on the right side of the top surface of the mounting frame 21. The wire rope 221 is coiled on the traction hoist 222. The wire rope 221 is drawn from the traction hoist 222. When the wire rope 221 subsequently pulls the prestressed steel strand, the traction hoist 222 reels the wire rope 221, causing the wire rope 221 to pull the prestressed steel strand, allowing the prestressed steel strand to be threaded through the bundled corrugated tube.

[0047] The rigid guide assembly 23 includes a stand 232 and a bundle threading machine 233. The stand 232 is vertically mounted on the top surface of the mounting frame 21, to the left of the traction assembly 22. The bundle threading machine 233 is mounted on the top surface of the stand 232. The traction end of the guide steel strand 231 first enters the bundle threading machine 233, exits the bundle threading machine 233, and connects to the wire rope 221. The bundle threading machine 233 drives the guide steel strand 231 to pass through the corrugated tube, thereby driving the wire rope 221 to be bundled. As the bundle threading machine 233 continuously feeds the guide steel strand 231 into the corrugated tube, both the guide steel strand 231 and the wire rope 221 are eventually passed through the corrugated tube.

[0048] The rigid guide assembly 23 also includes a mounting rod 234, a connecting rod 235, a mounting seat 236, a rotating shaft 237, and a guard frame 238; two mounting rods 234 are arranged at intervals in the front and rear, and the mounting rod 234 is an L-shaped structure. The left ends of the horizontal sides of the two mounting rods 234 are respectively fixedly connected to the left end surface of the mounting frame 21, and the vertical sides are located on the top surface of the left ends of the horizontal sides; the connecting rod 235 is arranged horizontally in the front and rear, and its two ends are fixedly connected to the upper part of the opposite side of the vertical sides of the two mounting rods 234; the mounting seats 236 are respectively arranged in the middle of the left end surfaces of the vertical sides of the two mounting rods 234, and bearings are provided in the mounting seats 236; the rotating shaft 237 is arranged horizontally in the front and rear, and its two ends are respectively rotatably connected to the bearings in the two mounting seats 236; the guard frame 238 is fixedly sleeved on the rotating shaft 237, and its rear side is open; the guide steel strand 231 is coiled on the rotating shaft 237. The guide strand 231 is stored in the rotating shaft 237. When in use, the guide strand 231 can be simply pulled out of the rotating shaft 237, making it easy to operate. After the guide strand 231 drives the wire rope 221 through the corrugated tube, the rotating shaft 237 is rotated to drive the wire rope 221 back into the rotating shaft 237, allowing the guide strand 231 to be recovered and convenient for the next bundle threading. The protective frame 238 effectively restrains the guide strand 231 on the rotating shaft 237, preventing it from falling out during the wire reeling and unreeling process, ensuring safety.

[0049] The rigid guide assembly 23 also includes a fixing rod 241 and a guide member 242. The fixing rod 241 is vertically mounted, its upper portion fixedly connected to the right side of the connecting rod 235, and its bottom portion is provided with a through-hole. The guide member 242 is located within the opening of the fixing rod 241 and is hollow with two open ends. The pulling end of the guide strand 231 first passes through the guide member 242 and then enters the stranding machine 233, ensuring smooth payout and take-up of the guide strand 231.

[0050] The machine also includes a lifting mechanism 5, which includes a gantry 51, a lifting hoist 52, and a cable 53. The gantry 51 is vertically arranged, with its bottom fixedly connected to the front and rear sides of the frame plate top. The lifting hoist 52 is located at the top of the frame 1. The cable 53 is coiled on the lifting hoist 52, with its traction end connected to the top surface of the gantry 51. The lifting hoist 52 reels or releases the cable 53, driving the gantry 51 to rise or fall, thereby driving the splint 11 to rise and fall, causing the traction and bundle-threading mechanism 2 to rise and fall, thereby adapting to corrugated pipes located at different heights.

[0051] The apparatus further includes a moving mechanism 6, which comprises a base plate 61, a moving motor 62, a gear 63, and a rack 64. The base plate 61 is located on the left side of the mounting frame 21. The moving motor 62 is a right-angle motor, mounted on the base plate 61, with its output shaft extending through the bottom surface of the base plate 61. The gear 63 is fixedly mounted on the output shaft of the moving motor 62. The rack 64 is horizontally mounted on the left side of the frame plate and meshes with the gear 63. The moving motor 62 drives the gear 63 to rotate on the rack 64, which in turn drives the mounting plate to move back and forth on the frame plate, allowing the traction and beam threading mechanism 2 to move back and forth, adapting to corrugated pipes at different horizontal positions. The moving mechanism 6 cooperates with the lifting mechanism 5 to adjust the traction and beam threading mechanism 2 to the corrugated pipes at different positions.

[0052] The bottom of the frame 1 is provided with universal wheels 12. The frame 1 moves via the universal wheels 12, making it easy to move the entire device.

[0053] The traction ends of the steel wire rope 221 and the guide steel strand 231 are both welded with limit blocks; the guide fixture 3 includes a guide fixing part 31, a guide head 32, and a through slot 311 on one side of the guide fixing part 31; the guide head 32 is hollow inside, with a conical structure at the left end and an open right end face. The right end of the guide head 32 is sleeved on the left side of the guide fixing part 31 and is connected to the guide fixing part 31 by a thread. When connecting, the guide steel strand 231 and the steel wire rope 221 are placed into the guide fixing part 31 through the through slot 311, and the limit block is located outside the left end of the first guide fixing block 31. The guide head 32 is then connected to the first guide fixing block 31, thereby fixing the guide steel strand 231 and the steel wire rope 221. When passing through the corrugated pipe, the limit block abuts the through slot 311 to prevent the guide steel strand 231 and the steel wire rope 221 from falling out. The tapered structure pulled to the left end can ensure a smooth threading process while preventing damage to the bellows.

[0054] In a further embodiment, the guide fixing member 31 includes a first guide fixing block 31a and a second guide fixing block 31b; the first guide fixing block 31a and the second guide fixing block 31b are integrally formed cylindrical structures, and the diameter of the first guide fixing block 31a is smaller than that of the second guide fixing block 31b, and the outer wall of the first guide fixing block 31a is connected to the inside of the guide head 32 by threads.

[0055] The traction clamp 4 includes a traction head 41; the traction head 41 is hollow inside, with a conical structure at the right end and openings at both ends. The diameter of the left end opening is smaller than the limit block of the wire rope 221. The inner side wall of the traction head 41 is circumferentially provided with a receiving groove 411 for placing the prestressed steel strand, and a card slot 412 is provided on the right side wall. When the steel wire rope 221 is connected to the prestressed steel strand bundle through the traction clamp 4, the traction end of the steel wire rope 221 is placed into the traction head 41 through the card slot 412, and each steel strand of the prestressed steel strand bundle is inserted into the traction head 41 from the other end, so that the steel strand is placed in the receiving groove 411, and the steel wire rope 221 is located between multiple steel strands; during the bundle threading process, the limit block on the steel wire rope 221 presses against the prestressed steel strand, so that the prestressed steel strand is pressed in the receiving groove 411, and the friction force is used to prevent the prestressed steel strand from falling off. At the same time, since the opening diameter of the left end of the traction head 41 is smaller than the limit block, the steel wire rope 221 will not fall out of the traction head 41 during the traction process.

[0056] The receiving groove 411 is provided with anti-skid lines 413. The anti-skid lines 413 in the receiving groove 411 increase the friction between the prestressed steel strand and the receiving groove 411, further preventing the prestressed steel strand from falling off.

[0057] The working mode of the present invention is:

[0058] The entire device is moved to the work site via the universal wheel 12 , and the position of the traction and beam-threading device is adjusted via the lifting mechanism 5 and the moving mechanism 6 according to the position of the component bellows.

[0059] The guide strand 231 is led out from the rotating shaft 237, passes through the guide member 242 of the guide assembly 24, enters the bundle threading machine 233, and then passes out of the bundle threading machine 233. The wire rope 221 is led out from the traction winch 222, and then the guide strand 231 and the traction end of the wire rope 221 are placed into the guide fixing member 31 through the through slot 311. After placement is completed, the traction head 41 is screwed onto the guide fixing member 31.

[0060] Place the guide fixture 3 into the corrugated tube, start the bundle threading machine 233, and the bundle threading machine 233 drives the guide steel strand 231 to be bundled, so that the guide steel strand 231 and the wire rope 221 are bundled into the corrugated tube synchronously until they extend out from the other end of the corrugated tube.

[0061] After the guide steel strand 231 and the wire rope 221 have been threaded through, the threading machine 233 is closed, the guide clamp 3 is removed, and the guide steel strand 231 is recovered. The wire rope 221 and the prestressed steel strand bundle are then loaded into the traction head 41 of the traction clamp 4, and the traction winch 222 is started to retract the wire rope 221, allowing the wire rope 221 to drive the prestressed steel strand bundle through the corrugated tube until the threading of the prestressed steel strand bundle is completed, thus completing the threading of the entire prestressed steel strand bundle.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
